Journal ArticleDOI
Direct full compensation of the aberrations in quantitative phase microscopy of thin objects by a single digital hologram
Lisa Miccio,Domenico Alfieri,Simonetta Grilli,Pietro Ferraro,Andrea Finizio,L. De Petrocellis,Sergio De Nicola +6 more
TL;DR: In this paper, a two-dimensional fit with the Zernike polynomials of the reconstructed unwrapped phase is performed to remove unwanted aberration in quantitative phase microscopy of thin objects.
Journal ArticleDOI
Automatic focusing in digital holography and its application to stretched holograms
Pasquale Memmolo,Cosimo Distante,Melania Paturzo,Andrea Finizio,Pietro Ferraro,Bahrain Javidi +5 more
TL;DR: An algorithm for automatically estimating the in-focus image and recovering the correct reconstruction distance for speckle holograms and a comparative analysis has been performed with respect to other existing algorithms developed for DH.
Journal ArticleDOI
A digital holographic microscope for complete characterization of microelectromechanical systems
TL;DR: Digital holographic microscopy (DHM) can be described as a non-invasive metrological tool for inspection and characterization of microelectromechanical structures (MEMS) as mentioned in this paper.
Journal ArticleDOI
Quantitative phase-contrast microscopy by a lateral shear approach to digital holographic image reconstruction.
TL;DR: It is demonstrated that it is possible to obtain quantitative optical phase measurement in microscopy by a new single-image-processing procedure combining the concept of lateral shear interferometry (LSI) within a digital holography microscope.

James R. Dunphy,Gerald Meltz,Mauro Varasi,Antonello Vannucci,Mario Signorazzi,Pietro Ferraro,Sabato Inserra Imparato,Claudio Voto +7 more
TL;DR: In this paper, an embedded optical sensor has a plurality of layers (10-20) and an optical fiber (21) with a fiber grating (28), disposed between the layers (14, 16).
